oniann sra'rns mam 2 ANDREW J. MORTON, DE LOS .ANGELES, CA-LIFORNI AT TWIN OIL-BURNER.

To all whom it may concern:

Be it known thatI, ANDREW J. MORTON, a citizen of the United States, residing at Los Angeles, in the county of Los. Angeles and elastic'fluid is used to spray oil into the fireboxor furnace, and to cause the same tobreak up and to become atomized and mixed with air for perfect combustion. v

Objects of the invention are to provlde an oil burner of this description'which is cheap and simple to manufacture; which will atomize the oil and-distribute it in the furnace in such a way as not'to be destructive to the side walls of the fire-box; also to provide for ready and convenientcleaning of the burner if it becomes clogged with accumulations of asphaltum, hardened carbon 5 or foreign matter.

the body of the burner from which the detachable plates have been removed. Fig. 1'

The accompanying drawings illustrate the invention. V

' Figure 1 is a perspective-view of a burner constructed in accordance with this invention. Fig. 2 is a perspective view of the burner elements dismantled, omitting the.

screwsand pipes shown in Fig. 1, the upper plate being turned upside down to expose the inside construction. Fig; 3'is a plan of is aplan of the separating plate detached. Fig. 5 is a View of the bottom of the burner Fig. 6 is a front view of the burner detached. Fig. is a longitudinal section of the burner on irregular line w w Figs. 3 to 6. Fig. 8 isa fragmental vertical section on line indicated at m 'm Fig. 5.

V The body of the burner comprises a stock '1, and a lip 2 projecting forwardly from the lower part of the stock, which is thus practically recessed to receive detachable superposed elements .to form mixing and discharge passages. Said stock qis provided with two superposed longitudinal bores 3,' 4, opening into the recess 5. The upper face of lip2 is channeled at 6,: 7, 8 to form-in conjunction with a superposed element an expansion chamber at 6 and two outlets at 7,

'8 opening forwardly therefrom, there being at the sides of the lip, two side walls 9, and

there also being at the' front a rib 10 separating the two outlet channels 7 '8. ,The tops of said side walls and rib'are in a com- Specification ofLetters Patent. PatentedNOV.2, 1915. 4

monhorizontal plane toward which the floors of the channels 7, 8 slope: upwardly. The wall 11 of the stock at the rear of the lip is inclined rearwardly and superposed plates 12 and 13 rest-against said wall.

The separating p1ate'12 may be a piece of sheet metal of any appropriate thickness, say for instance, "about of an inch thick,

the same'bein'g fittedupon'th'e tops'of the side walls and the rib. I

" The upperlplate orca'p l3'is channeled like the lip so as to form, in conjunction with the separating or intermediate plate,

the distributing chamber lhand the outlets 15, 16 therefrom; there being at the sides of said'upper plate two side walls 17 18 and there also being a rib 10 lying between and separating the outletchannels. The lateral extension of the issuing jets of expansive fluid" will be effected mainly by the expan sion of the fluid after leaving the channels.

at some distance from the burner, the result being that the edges of the two flat jets will impinge upon the air close to the burner in the space between said jets, and will'en'train the-airinto the middle 'of'th'e final'wide flat jet resulting from the union of the tWoiss'ug fi jetsof steam. I 1 w i In practice said jets strike upon each other. 3

The burner may be installed by screwing I the steam and oil pipes 19, 20 into the bores 3, 4 in -the stock of the burner 'said'pipes then being connected in any usual way with the sources of steam and oil-supplies; The

plates 12, 13 are fastened in superposed position on the lip 2 by means of machine screws 21, 22; said fscrews being provided with cylindrical bodies b to pass 'thr'ough the holes 23'," 2-prepared in, the plates to receive said .bodies.

threaded ends 0 of the machine screws.

There are preferably three machine'scre'ws used at the tip of the burner, and two other in the lip. The ends of theplatestha't are to abut against the Wall are beveled'to fit The lip is provided with threaded'holes 25, ready to receive the nels.

tightly against the wall, and when the five screws are screwed home firmly, they close the joint between the plates, the stock, and the lip, so that no steam or oil will escape from the burner except through the channels provided therefor.

The tip of the burner is provided with two forward extensions 27, 28 each of which is outwardly curved thus leaving a central recess 29, adjacent the front ends of the ribs 10, so as to give free access of air to the space between the jets issuing from the chan- The bottom of the lip 2 and the top of the top plate, are also recessed as indi cated at 30 and 31, to allow a freer passage of air to the recess between the jets.

In practical operation the steam expands in the expansion chamber therefor and flows through the outlet ports under a regulated pressure determined by the steam pressure supplied through the steam pipes, thin flat twin steam jets being thus discharged edge to edge in a common plane. also be supplied under an appropriate pressure and will fill the feed chamber and the outlet ports leading therefrom so that the liquid hydrocarbon will be delivered in a predetermined stream to the space above the steam outlets and will fall onto the fiat issuing jets of steam. By preference the steam outlets are slightly wider than the oil outlets, so that the oil streams will not escape downward past the steam jets that are designed to receive them. The action of the steam or other expansible fiuid used, will be to tear up the oil and to thoroughly mix the same with entrained air,'at the middle as well as at the edges of the final united jet, and when ignition occurs, the fuel is vaporized and burnt in a highly economical and eflicient manner, expansion of the gases sired form.

practically filling the fire-box, not shown.

The outlets for the oil are directly above the outlets for steam and are narrower than and spaced farther apart than the steam outlets, so that air is entrained to the steam between the oil ets or streams, thus increasother suitable metal.

By changing the angle-of the inner face of theside walls, the jets are made to flow in any desired direction so as to avoid destructive action on the side walls of the furnace or fire box- Such change-may be made by filing or otherwise cutting said walls as required.

In case of clogging or stopping of the The oil will channels, the screws may be removed and the plates taken off and the channels cleaned out. Thereupon the plates may be restored and the burner will again be ready for operation.

It is thus seen that I have provided superposed chambers and pairs of outlets therefrom, the pairs of outlets being spaced apart to admit air to be entrained between them, thus producing twin jets that become united after entraining air between them.

I claim: v

4. A burner comprising a body, a lip, and plates arranged to form two superposed chambers and pairs of outlets therefrom, the pairs being spaced apartfrom each other to admit air to jets issuing from the outlets, and means to fasten the parts together.
